Serverless-wsgi

Features

- Adds support for packaging handlers inside directories (i.e. setting the wsgi handler to something like `dir/app.handler`).

Features

- Added unit tests.

Bugs

- Internal requirements file was not included when user requirements file was present.

Features

- Enable using the requirements packaging functionality alone, without the WSGI handler. This is enabled by omitting the `custom.wsgi.app` setting from `serverless.yml`.
- Load provider and function environment variables when serving WSGI app locally.

Bugs

- If no `requirements.txt` file is present and the WSGI handler is enabled, make sure to package werkzeug.
